Meta-analyses are integral in supporting research grant proposals, shaping treatment guidelines, and influencing health policies. They are also pivotal in summarizing existing research to guide future studies, thereby cementing their role as a fundamental methodology in metascience.
A metamodel is a model of a model, and metamodeling is the process of generating such metamodels. Thus metamodeling or meta-modeling is the analysis, construction, and development of the frames, rules, constraints, models, and theories applicable and useful for modeling a predefined class of problems. As its name implies, this concept applies ...

[1] [2] Meta-leadership has been “derived ...
The aim of the PRISMA statement is to help authors improve the reporting of systematic reviews and meta-analyses. [3] PRISMA has mainly focused on systematic reviews and meta-analysis of randomized trials, but it can also be used as a basis for reporting reviews of other types of research (e.g., diagnostic studies, observational studies).
The GRADE approach (Grading of Recommendations Assessment, Development and Evaluation) is a method of assessing the certainty in evidence (also known as quality of evidence or confidence in effect estimates) and the strength of recommendations in health care. [ 1] It provides a structured and transparent evaluation of the importance of outcomes ...
Metanarrative. In social theory, a metanarrative (also master narrative, or meta-narrative and grand narrative; French: métarécit or grand récit) is an overarching narrative about smaller historical narratives, which offers a society legitimation through the anticipated completion of a (as yet unrealized) master idea.
Meta CEO Mark Zuckerberg took to Instagram on Tuesday to call out the tech industry, saying it should focus its generative AI efforts on open models rather than closed ones like those developed by ...
This bias distorts the results of meta-analyses and systematic reviews. For example, evidence-based medicine is increasingly reliant on meta-analysis to assess evidence. Conceptual illustration of how publication bias affects effect estimates in a meta-analysis. When negative effects are not published, the overall effect estimate tends to be ...
